ABSTRACT:
An energy efficient refrigerated display cabinet having glass barrier doors and one or more guard air bands to protect the primary refrigerated air band. A single guard air band is circulated about the primary refrigerated air band in order to protect the same from contact with the inner walls of the cabinet or the ambient air upon opening of the barrier doors. The cabinet can be provided with an air defrost system in which ambient air is taken in through ports in the cabinet which are selectively closed by gates or through a gap between the barrier doors and the associated access opening. An ambient air band can also be provided for circulation across the outer surface of the barrier doors in order to slightly raise the heat transfer into the glass panes in order to aid reduction of moisture condensate formation on the glass panes.
